RECLlNlNG-CHAIR.

l u SPECIFICATION forming part of Letters Patent No. 242,733, dated June7, 1881.

` Application tiled Februaryui. 1880.

`valid, dental, or barber chairs which are adapted to assume either anupright,reclining,

Ior horizontal position.

The object of the invention is to provide a reclining-chair in whichprovision is made for varying positions of the component parts thereofto enable the occupant to place him-` self in position from a sitting toa reculnbent position,-and which is designed to be used by invalids, byphysicians as anv operating.

chair or lounge, and by dentists and barbers.

My improvement consists, iirst, in the combi-` nation, with perforatedsegments, of spring- -act'uated bolts and a lever Vhin ged to a pivotedblock,V whereby such segments are locked and released by the action ofthe lever and bolts and clamped by the pivoted block, substantially ashereinafter set forth.

My improvementconsists,further, in ahin ged and pivoted cam-leverconstructed with a lip, and adapted to be used in operating the slidingllock-bolts, as a` guide for the segment, and as a brake to the segment,to preventthe chairback from falling too fast when the weight of thebody is placed upon it.

My improvement consists, further, in combining with a hinged head-restrods 0r tubes attached to the body of the chair for the purpose ofraising the head-rest automatically as the back approaches a recumbentposition.

In order that the invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure l is a perspective view of my improved char. Fig. 2 is a verticalsection thereof. Fig. 3 is a horizontal section on the line 3 3, Fig. 2.Fig. 4t is a perspective view, showing mode of connecting head-restrods. Fig. 5 is a side view, showing the parts adj usted so as toconstitute a lounge.

The chair is constructed with a firm support, A, seat B, leg-rest C,foot-rail D, back port are side plates, G G, secured by bolts g g g g',which form pivots for the leg-rest frame H and back-frame Irespectively.

. J J are segment-plates fnlcrumedl to the plates G G by studs j j, andK K are arms hinged to the upper ends of the segments by studs 7c k, andtothe back-frame I by studs 7c k. The segments are constructed withholes or depressions j j', and are provided at their lower ends withpintlesjzjg, which engage in recesses l l of and support slotted platesL L, hingedto the leg-rest frame H by means ot' studsff. y

M'M are theside frames of the head-rest,

-hinged to lugs or ears li i, and raised or lowered means of theset-screw O, thereby affording a means for regulating the angle at whichthe head-restV shall rest. The adjustment of the head-rest may beeffected either before or after the chair-back is lowered. By simplyloosening the screw O before the back is lowered the block 0 will,during the lowering of the back, slide down the lower tube, N, andthereby leave the head-rest in the same position it assumed while thechair-back was in its upright position. The descent of the lower rod ortube, N, may be stopped at any time by simply tightening the screw O,thus leaving the lower rod free to operate on the head-rest to push itforward or, by lowering the back while the lower rod is held rigid, andthen loosening the screw O, the angle at which the head-rest shallremain can easily be regulated by pushing the upper rod and its attachedblock o along the lower rod. This arrangement of devices, it will bereadily seen, admits of the easy regulation ofthe position of thehead-rest g any desired inclination may readily be imparted to it at anytime by simply loosening the screw O and sliding the block o along thelower tubea much more effective arrangement than where v the head-restis supported upon jointed rods or bars without capability of beingshortened or lengthened and rigidly clamped by screw. Where thehead-reet is supported by one entire rod or by a series of jointed rodsthe nice and rigid adjustment of the head-rest obtainable by mtvdevicecannot be secured.

Beneathdie seat is a cross-piece, Q, on which is pivoted, by a bolt, q,a cross-bar, R, having hinged to each end bolts S S, which pass throughsuitable openings a a in the support A to permit them to engage with theholes or depressions j 7" in the segments J J The bolts are inserted bymeans of a spring, T, adapted to draw the cross-bar It so as to forcethe bolts outward. The bolts are limited in their outward movement bythe cross-bar coming in Lcontact with a stop-pin, q. The bolts areretracted by means of a hinged and pivoted cam-lever, U, mounted on aplate, V, adapted to press in a push-rod, u, connected to one end of thecross-bar. The lever U has its cam portion u pivoted at a2, so as topermit it to turn and be pressed against the segment and thus form abrake thereto, while its lip a3 forms a guide to the segment. a4 is thehinge which permits the handle portion a5 to be pressed sidewise againstthe push-pin. On the opposite side of the support A is a plate,W, havinglips w w, and adapted to form a guide and support for the locking-bolt Sand segment J For forcing the bolts outward any kind of spring may beused of any suitable construction. It may be connected with cross bar,lever-rod, or lock-bolts, which would obtain the same results.

In Fig. 5 I represent, in dotted lines, the position ot' the cam-leverwhen it is desired t0 remove or apply thesegment.

When the back is in its lowest position it is supported by the armswhich rest upon the side plates.

Having thus described my invention, the following is what I claim as newtherein and desire to secure' by Letters Patent:

1. In combination with the perforated segments J J the spring-actuatedbolts S S', and the lever U, hinged to thepivoted block, Whereby thesegments are locked and released by the action of said hinged lever andbolts, and clamped by said pivoted block, as set forth.

2. In combination With the perforated segments and the hingedulever U,the pivoted block having cam and lipa2 a3, serving as a guide, clamp,and brake for the segments, as set forth.

3. In combination with the back, scat, arms, and foot-rest, the pivotedsegments and the pivoted cam-lever, acting as a brake for said segments,as set forth.

4. The combination, with the frame A and tilting back I, of thehead-rest F, hinged at its lower end to the lugs or ears i i, arm P,projecting from the rear of said head-rest, rods N N, block o, andset-screw O, one of said rods being pivoted at its upper end to said armP, while its lower end is rigidly attached to the block o, the other rodbeing pivoted at one end to the base of the chair, While its other endpasses through a hole in the block o, substantially as and for thepurpose set forth.
